CSIR-CRRI and CSIR-IIP transfer indigenous bio-bitumen technology to industry

Key facts

• Bio-bitumen is produced by converting farm residue, like paddy straw, through a process called pyrolysis.
• A 100-metre trial stretch using bio-bitumen has already been laid on the Jorabat–Shillong Expressway (NH-40) in Meghalaya.
• The pyrolysis process also yields energy-efficient gas and high-grade carbon for applications from batteries to water purification.
